i would really press for a new engine, they trashed it. a few minutes without oil is obviously bad news, and it may not manifest itself for a period of time. what good does it do you if in a year the bearings fail. there is no possible way that engine is the same engine before they ran it out of oil. i'm in the aviation business and no one in their right mind would ever use that engine again...without a rebuild. i realize its a car and not an aircraft, no one gets hurt when a car engine fails...usually. but what the heck we all love our MBs and i maintain mine to a very high standard. it will take you "forever" to deal with the insurance company but in the long run it will result in a better car. good luck.
